JWST has revealed that galaxies were spreading carbon, oxygen, and other heavy elements through space just 500 million years after the Big Bang. The surprising discovery suggests the young universe became chemically enriched much earlier than expected, potentially erasing traces
JWST has revealed that galaxies were spreading carbon, oxygen, and other heavy elements through space just 500 million years after the Big Bang. The surprising discovery suggests the young universe became chemically enriched much earlier than expected, potentially erasing traces of its very first stars.

Scientists find a surprising clue to why the universe’s expansion doesn’t add up
Tiny magnetic fields created shortly after the Big Bang may help explain the long-running disagreement over how fast the universe is expanding. Detailed simulations show that these primordial fields could have changed the formation of hydrogen in the early universe, affecting the

Quantum interactions may have locked early universe's fields into existing energy states
The universe may be trapped in its own comfort zone, and a researcher in the College of Engineering and Computer Science has helped explain why it cannot seem to leave. A new study suggests the universe could be locked into its current state by the same kinds of quantum effects t

Sharks can hear nearly 250 feet away and pinpoint the source
Wild blacktip sharks can detect low-frequency sounds from nearly 250 feet away, according to experiments conducted off the Florida coast. The sharks not only heard the sounds but sharply changed direction away from them, suggesting they could pinpoint where they were coming from.
